One Workflow, Infinite Agents: Context-Aware AI ChatBot for Multi-Domain Platforms

🧠 Centralized Intelligence Hub: Multi-Site AI Assistant with Smart Routing & Vector Search

​Stop building and maintaining separate AI chat services for every website or client. This powerful n8n workflow is the central intelligence hub that dynamically routes user queries to the correct context-aware agent, instantly delivering tailored, memory-enabled support across your entire portfolio.

​This template uses community nodes and is fully compatible with the self-hosted version of n8n.

​🔥 What This Workflow Delivers

​This system enables a single, scalable solution to manage personalized, high-performance virtual assistants across multiple domains or pages.

​• Scalable Multi-Site Support: Deploy infinite AI assistants from a single workflow. The Smart Routing logic ensures that queries from Site A always go to the Site A agent, eliminating confusion and cross-talk.

• ​Deep Context & Memory: Agents use Pinecone vector search for up-to-date, context-aware responses and SQL-based memory for consistent, multi-turn conversations, making the assistant truly helpful.

• ​Hyper-Personalized Answers: Agents are customized per website with site-specific Pinecone namespaces and predefined system prompts to keep every response relevant to the originating domain and page.

• ​Developer-Friendly Integration: Starts with a simple Webhook input and ends with an immediate response, making it perfect for embedding into any existing web platform.

​⚙️ The Contextual Intelligence Engine (How It Works)

​The system processes incoming user queries through a single pipeline, ensuring seamless context isolation at every step:

1. ​Input & Identity: The Webhook Trigger receives the user's question, along with critical metadata: query, userId, site, and page identifiers.

2. ​Smart Routing: A powerful Switch node instantly directs the request to the specific AI agent trained for that site value.

3. ​Contextual Processing: The designated agent uses the OpenAI GPT-4/3.5 model in conjunction with the site-specific Pinecone vector store (for knowledge) and SQL memory (for conversation history).

​4. Final Delivery: The response is packaged and sent back to the originating website via the Respond to Webhook node.

​✅ Highlights

​• Architecture: Modular agents for scalable, multi-site support.

• ​Intelligence: Context-aware vector search (Pinecone) and multi-turn memory (SQL).

​• Security: No hardcoded API keys.

​• Setup: "Each workflow includes an easy installation guide so you can set it up in minutes.”
